Jonathan Barragan took victory in his home Grand Prix of Spain, at Bellpuig on Sunday, after 1-4 race results.
The Silver Action KTM star stormed to a ten-second victory over Honda's Clemet Desalle in race one, when reigning world champion David Philippaerts was third, before securing the overall by three points over Philippaerts courtesy of his fourth place in race two.
Barragan's victory marked the first ever home win by a Spanish rider.
Despite riding with a broken finger, sustained in a clash with countryman and world championship leader Antonio Cairoli last weekend in Portugal, Philippaerts put his Monster Yamaha third in both races - while Cairoli was once again in the thick of the action.
Red Bull Yamaha's MX1 rookie managed only eighth in race one after clashing with CAS Honda's Billy Mackenzie and then Monster Yamaha's Josh Coppins.
“Cairoli attempted a crazy overtaking move that just put both of us on the floor,” said Mackenzie, who was second at the time. “I don't know what he was thinking.”
Cairoli recovered quickly from that early race clash, but his collision with Coppins left the Sicilian with an injured rib.
"When I crashed with Josh it was my fault because I was going for his line and just caught his back wheel," he said. "With Mackenzie the first time I think it was a normal pass but he cut the line and we both went down.
"My fuel tank was actually damaged after that so I was going easy on the gas because I did not want to run out before the end of the race. I still could make the best lap-time and the moment with Josh was a shame, it also hurt some of my ribs although the pain was not so bad by the start of the second race."
Nevertheless, the double MX2 champ fought through the field spectacularly in race two, snatching victory by just over a second from Factory KTM's Max Nagl to hand the Italian third overall behind Barragan and Philippaerts.
"I lost some time at the beginning of the second moto but I found the right lines and even copied a few from Jonathan when he overtook me for a while!" he revealed. "I felt really good, and when I saw Nagl make a mistake I pushed hard for the win."
With Suzuki's Ken de Dycker crashing out of race one, and only twelfth in race two, Cairoli is now 36 points clear of Barragan in the world championship, with de Dycker 12 points further back in third.
